Quite concerning findings in the following study.[1]
Oleic acid accounts for 55-83% of the fatty acid content in olive oil. Measured fatty acid content in olive oil is 472.63–7751.20 μg/ml.[2] Oleic acid in Syrian olive oil is 3785 ug/mL.
Since we might have become more sensitive to 5-ARI’s, it might be wise to avoid oleic acid. Which is extremely hard since it is in many foods (vegetable oils like olive, canola, sunflower, but also in nut oils, meat, poultry, cheese and many processed food).
The reduction for 5-ARI activity is insane.
